First of all thank you for your answer.
I can't use a square voltage thats why i can't use FET or a Mosfet. The disc behave like a capacitor.
When i want o graduate a ultrasound with a frequency with 70 kHz how high must be the current when the input voltage is max 400 V and the capacitance...
Hey guys,
I need your help. I am a bit lost. I have to build an amplifier circuit for a piezoelectric disk for ultrasound generation in university.
The technical data (piezoelectric disk):
Resonant frequency = 80 kHz
Electrical capacity = 35 nF
Max. Supply voltage = 400 V
In the university I...
